On a material thighs and their laying 47 embryos and prefetals human female from 6 to 12 weeks of prenatal development by scanning electron microscopy were studied morphofunctional features of chondrocytes in different geochemical conditions of the Lower Volga (Astrakhan) and North Caucasus (Makhachkala). On electronograms determined by absolute surface membrane of the endoplasmic reticulum of chondrocytes. In stage 6 - 8 weeks of prenatal development of the population of chondrocytes laying of femurs of the person is uniform. Absolute surface membranes of the endoplasmic reticulum in both geochemical zones were not statistically different. In epiphyseal departments laying of femurs prefetal 9 and 10 weeks of fetal development and in Astrakhan and Makhachkala revealed the presence of two types of chondrocytes (I and II), adapted to the synthesis of a protein or polysaccharide parts of the cartilage matrix. Mode absolute surface endoplasmic reticulum membranes for both types of chondrocytes in Makhachkala shifted toward higher values compared to Astrakhan, which indicates the intensity of the synthesis of cartilage matrix components in the cells of the geochemical zones with higher mineralization.
